Book

Book actions make Google Search an entry point for discovering books and authors, enabling Search
users to quickly buy the books that they find directly from Search results. As a provider of e-books,
you can provide a feed of data to Google using the structured data schema below.

To ensure robust
coverage and better serve our users, this feature is currently limited to
book providers that have broad book availability. If you would like to participate, register your
interest in our form. Indicating interest in this feature does not guarantee participation.

Examples

The user’s query can indicate an intent to find a book, such as
a book title, like The Catcher in the Rye, or the books of J.D. Salinger. For
relevant queries, we might show a Knowledge
Graph card for the book. Read more about managing your Knowledge Graph data. Read actions, which are incorporated into the cards, display
options for acquiring the book. Through links you provide, read actions
send users directly from the Knowledge Graph card to a book page on your
site or app.

Guidelines

If you have duplicate pages for the same content, the link should be the
canonical URL that
contains the book title and other book information.

Upon clicking a read action link, your user should be sent to a page that directly
supports the acquisition of the book.

Read action links must point to a page where users can acquire the content. Read action
links must not point to pages that to click more pages to acquire the content or view more
details, such as a search results page or product summary page.

Structured data type definitions

You must include the required properties for your content to be eligible for display as a rich result.
You can also include the recommended properties to add more information about your content,
which could provide a better user experience.

Book

While the full definition of Book is available at
schema.org/Book, you only need to define
the properties listed below. You must define the following required properties for every book
in your site.

The ISBN of the tome. The ISBN can be either 10 or 13 digits, but we recommend 13 digits if
available. Use the ISBN of the print book instead if there is no ISBN for
the edition being described; for example, for the Kindle edition.

Globally unique ID of the volume in the form of a URL. The ID should be stable
and not change over time. It should also be distinct from the ID used
for the book. The URL is treated as an opaque string and does not
have to be a working link.
